This paper focuses on the parameters of the technological regime for the regeneration of aluminosilicate adsorbents on natural gas processing plants adsorption type on the dehydration of methanol from natural gas. The object of this study were the non-hydrocarbon fraction of liquid products of the purification of natural gas from an adsorption unit on silica gel with countercurrent regeneration. Gas treatment plants was optimized using BASF KC-Trockenperlen silica gels and microporous silica gel adsorbents (АСМ). The direct-flow regeneration technology on natural gas processing plants with adsorption purification оn aluminosilicate adsorbents contributes to a more efficient reaction of the conversion of methanol to dimethyl ether and his process reduces the volume of non-hydrocarbon waste fraction. Decreasing methanol concentrations reduces atmospheric emissions and saves fuel gas consumed by a stationary thermal treatment unit.

Shell And Tube

The design requirements for a large shell and tube vertical heat exchanger (to be used in a sulfur recovery tail gas treatment unit) included startup, shutdown and upset conditions that would subject the exchanger to significant temperature changes. The exchanger was designed to the requirement of the ASME Boiler and Pressure Vessel Section VIII Division 1 [1]. A detailed analysis of the thermal profiles and related stresses was performed to confirm the use of a flexible tube sheet design. The heat exchanger uses high pressure superheated steam on the shell side to heat a low pressure process gas on the tube side. The heat exchanger was sized and thermally rated, using commercially available analysis software. The proposed design was analyzed by Finite Element methods that included both thermal and stress analysis. These evaluations confirmed that a flexible tube sheet design was satisfactory when using specific dimensions.

Flexible Transfer Lines

The demand for natural gas from offshore fields is continuously increasing. Especially future production from Arctic waters comes into focus in context with global warming effects leading to the development of a dedicated technology. Relevant approaches work with floating turret moored production terminals (FLNG) receiving gas via flexible risers from subsea or onshore fields. These terminals provide on-board gas treatment and liquefaction facilities as well as huge storage capabilities for LNG (Liquefied Natural Gas), LPG (Liquefied Petrol Gases) and condensate. Products are transferred to periodically operating shuttle tankers for onshore supply reducing the need for local onshore processing plants providing increased production flexibility (future movability or adaptation of capacity). Nevertheless, in case of harsh environmental conditions or ice coverage the offshore transfer of cryogenic liquids between the terminal and the tankers becomes a major challenge. In the framework of the joint research project MPLS20 ([1]), an innovative offshore mooring and cargo transfer system has been developed and analyzed. MPLS20 is developed by the project partners Nexans ([2]) and Brugg ([3]), leading manufacturers of vacuum insulated, flexible cryogenic transfer pipes, IMPaC ([4]), an innovative engineering company that has been involved in many projects for the international oil and gas industry for more than 25 years and the Technical University (TU) Berlin, Department of Land- and Sea Transportation Systems (NAOE, [5]), with great expertise in numerical analyses and model tests. The overall system is based on IMPaC’s patented and certified offshore ‘Mooring Bay’ concept allowing mooring of the vessels in tandem configuration and simultaneous handling and operation of up to six flexible transfer pipes in full aerial mode. The concept is outlined to operate with flexible transfer lines with 16-inch inner diameter like the newly designed and certified corrugated pipes from Nexans and Brugg. The mooring concept and its major subsystems have proven their operability by means of extensive numerical analysis, model tests and a professional ship handling simulator resulting in an overall transfer solution suitable to be used especially under Arctic conditions like addressed by the EU joint research project ACCESS (http://access-eu.org/). The paper introduces the new offshore LNG transfer system and focuses especially on its safe and reliable operability in the Arctic — with ice coverage as well as in open water conditions.

Natural Gas Sweetening

Natural gas is often contaminated with acid gases; commonly hydrogen sulfide (H2S) andcarbon dioxide (CO2). In addition to their offensive odor and high toxicity, acid gases can cause serious corrosion problems in a gas plant due to their acidic nature and may reduce the efficiency of gas treatment processes. Therefore, several natural gas sweetening processes have been developed for the removal of acid gases. In present work, we report the employment of amine-functionalized graphene hybrid for adsorption of acid gases. Graphene was selected as a solid sorbent due to its very high specific surface area and ability to undergo various chemical transformations.Considering high affinity of amines towards H2S, an aminated polymer, polyethylenimine (PEI) was used as a functionalizing agent. The resulting hybrids were characterized using Fourier Transform Infrared spectroscopy (FTIR), X-ray Photoelectron Spectroscopy (XPS), elemental analysis, X-ray Diffraction analysis (XRD), and Thermogravimetric Analysis (TGA). These hybrids are envisioned as materials with high H2S sorption capacities and hold great promise in natural gas sweetening applications.
